The joint pointing knife (rubber spatula) should be used to scrape the joint sealant In order to prevent the yellow sand or quartz sand with high hardness in the joint filler from scratching the ceramic tile.
the phenomenon of “white mold” on the surface).
B.
Through the modification of additives, it has good weather resistance and hydrophobicity that ordinary cement mortar does not have.
E.
Therefore, the determination of hue should be made only after coating the template.
The joint filler shall be scraped into the joint tightly; 4.
When it is used for interior decoration, the kitchen and balcony expect it and the ceramic tile to jointly shoulder the important task of anti-seepage.
I can tell you that when the water leakage reaches the house downstairs, they have done waterproof and also tested it.
In 2006, the state has formulated the building materials industry standard – ceramic wall and floor tile joint filler (JC / t1004-2006).
6.
After cleaning and hardening, use sponge to absorb water to remove the stains on the surface of ceramic tile.
Construction method and precautions of ceramic tile joint sealant Introduction to the construction method of ceramic tile sealant ceramic tile is a common decoration material in home decoration.
It is used for exterior wall porcelain Brick facing joint filling: when it is windy and rainy, the joint filler will give full play to its excellent hydrophobic performance, so that the rainwater will not penetrate into the wall and flow to the ground along the wall.
Some of our students will say that the waterproof in my home is very good, and there is no water leakage after testing for 48 hours.
Used for filling ceramic tile joints and pasting mosaics.
It forms a double insurance for your waterproof system.
The normal uranium surface ceramic tile can be cleaned with clean water.
A.
Caulking agent construction is a relatively easy to ignore link in family decoration.
For mixing, first add water into the bucket, slowly add the powder, and constantly stir until it is uniform, no particles and in the shape of toothpaste, then stand for 5-10 minutes, and then mix slightly before use.
F.
If the water absorption of the ceramic tile surface is too high and the joint filler penetrates into the ceramic tile, it shall be cleaned with ceramic tile cleaning agent.
3.
After the ceramic tile is pasted, the joint filler construction shall be carried out for a long time as possible to make the joint filler fill the ceramic tile bonding The gap after the mortar shrinkage makes the joint filling more dense and firm.
Many people may have learned about the paving of ceramic tile, so the construction of ceramic tile sealant may not be very clear.
After the construction of the joint filling agent, if there is “return to alkali”, it can be cleaned by brushing dilute oxalic acid..
When positioning and paving the cross, positioning the cross first can improve the construction efficiency, make the tile paving fast and convenient, and make the tile gap after paving uniform, neat and beautiful, so as to improve the tile paving effect.
the bottom treatment mortar joint shall be cleaned.
It will give full play to its good hydrophobicity Yes, even if you soak in the water for a long time, only a small amount of water can penetrate.
Due to different construction environmental conditions, water mixing volume and construction methods, there will be differences in hue.
Through the interpretation of the standard, it is not difficult to see that the joint filler is a building material with certain wear resistance, low shrinkage, certain flexural and compressive strength and low water absorption.
During construction, the joint sealant must be mixed evenly with a certain proportion of clean water, and the dry powder must not be directly scraped into the joint; 2.
What is the joint sealant and what is its function? Some students say that the joint sealant is white cement, which is only white.
If there is debris, cement block or ponding, it can be removed in advance; If the mortar joint is too dry, it can be properly wetted.
At the same time, when the cement in the mortar is hydrated, Ca (OH) 2 will be produced, and the joint filling agent is easy to return to alkali (i.e.
Plastered joint after plastering, the mortar joint shall be evenly plastered and pressed with a mortar joint spatula before hardening.
What problems should we pay attention to in the construction of joint sealant And? 1.
The bathroom, which has been tested by water for a long time, will jointly check the first pass for you with the ceramic tile.
5.
C.
Mixing method: common type: add 20kg powder and 56kg clean water; Wide seam type: 20kg powder added with 45kg clear water; Common type: 5kg powder added with 23kg water; Wide seam type: 5kg powder and 12kg clean water; D.
The joint filler is a modified cement mortar.
If it cannot be cleaned due to improper early construction and has to be cleaned with hydrochloric acid, dilute the hydrochloric acid to the concentration of 3%, and then wash it off immediately with clean water to prevent residual acid, because hydrochloric acid has a certain impact on the color of mortar joint.
In fact, joint sealant is a kind of building material introduced from Europe.
